Answer:
The answer is A, D=65h
Step-by-step explanation:
This is because D is representing how far you drove, so you can only drive 65 mph. And that will be 65*h=D. Hope this helps!
The solution is Option A.
The distance traveled is calculated by Distance D = 65h , where h is the number of hours
What is Speed?
Speed is defined as the rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude
Speed = Distance / Time
Given data ,
Let the distance traveled be represented as D
Now , the value of D will be
Let the speed be represented as S = 65 miles per hour
Let the time required to travel a distance of D be represented as = h
where h is the number of hours
So , the distance D is calculated from the formula
Speed = Distance traveled / Time required
Substituting the values in the equation , we get
65 = D / h
Multiply by h on both sides of the equation , we get
D = 65h
Therefore , the value of D is 65h
Hence , the equation will be D = 65h where h is the number of hours and D is the total distance

Process of elimination. None of the others make sense.
Answer:
x = 2 or x = -4
Step-by-step explanation:
Solve for x over the real numbers:
-x^2 - 2 x + 8 = 0
Multiply both sides by -1:
x^2 + 2 x - 8 = 0
Add 8 to both sides:
x^2 + 2 x = 8
Add 1 to both sides:
x^2 + 2 x + 1 = 9
Write the left hand side as a square:
(x + 1)^2 = 9
Take the square root of both sides:
x + 1 = 3 or x + 1 = -3
Subtract 1 from both sides:
x = 2 or x + 1 = -3
Subtract 1 from both sides:
Answer: x = 2 or x = -4

Given that (-1,7) is on the graph of f(x), find the corresponding point for the function f(x+3)
Answer:
(-4,7)
Step-by-step explanation:
Given
A point on f(x) = (-1,7)
Required
Find the coordinates of f(x+3)
The given parameter can be rewritten as
[tex]f(-1) = 7[/tex]
We're to solve for [tex]f(x+3)[/tex]
By comparing [tex]f(-1) = 7[/tex] to [tex]f(x+3)[/tex];
The expressions in the bracket implies that
[tex]-1 = x + 3[/tex]
Subtract 3 from both sides
[tex]-1 - 3 = x + 3 - 3[/tex]
[tex]-1 - 3 = x[/tex]
[tex]-4 = x[/tex]
[tex]x = -4[/tex]
Stil comparing
[tex]f(-1) = 7[/tex] to [tex]f(x+3)[/tex];
If f(-1) = f(x + 3) then
[tex]f(x +3)= 7[/tex]
Hence, the coordinates of f(x+3) is (-4,7)
For a randomly selected driver, are the events "driving while using a cell phone" and "having a traffic accident" independent events? Explain your answer. PLEASE HELP :(
Answer:
Let's denote:
The event of driving while using a cell phone: A
The event of having a traffic accident: B
The event of driving while using a cell phone and having a traffic accident: A⋂B
P(A) = 11% = 0.11
P(B) = 5.26% = 0.526
P(A⋂B) = 28% = 0.28
If event A and event B are independent (it means the cause of a traffic accident is nothing related to driving while using a cell phone), then:
P(A) x P(B) = P(A⋂B)
Let's check:
P(A) x P(B) = 0.11 x 0.526 = 0.05786 and not equal to P(A⋂B) = 0.28
=> Event A and event B are not independent. In other words, they are related. (it means driving while using a cell phone is one of the reasons for having a traffic accident)

HELP PLEASE!!! I need your guys help on this question.
Answer:
Area of a trapezium = 1/2(a+b)×h
where a and b are parallel sides of the trapezium
h is the height
First question
We must first find the height of the trapezium using Pythagoras theorem
That's
h² = 8² -3²
h =√ 64 - 9
h = √ 55m
a = 7m
b = 10+3 = 13m
Area of the trapezoid = 1/2(7+13)×√55
= 1/2×20×√55
= 74.16
= 74m² to the nearest tenth
Second question
We use sine to find the height
sin30° = h/12
h = 12 sin 30°
h = 6 in
Let the other half of the parallel side be x
To find the other half of the parallel side we use Pythagoras theorem
That's
x² = 12²- 6²
x = √144-36
x = √108
x = 6√3 in
So for this trapezoid
a = 9 in
b = (9 + 6√3) in
h = 6 in
Area of the trapezoid = 1/2(9 + 9+6√3) × 6
= 1/2(18+6√3)×6
= 85.176 in²
= 85 in² to the nearest tenth
Hope this helps you
Answer:
The first (left) trapezoid's area is [tex]10\sqrt{55}[/tex]m or ≈ 74.2m²
The second (right) trapezoid's area is [tex]54 +18\sqrt{3}[/tex] or ≈ 85.2 in²
Step-by-step explanation:
First trapezoid (left):
Because the first trapezoid is a normal trapezoid, we can use the equation [tex]A = \frac{a+ b}{2} * h[/tex] Where a is equal to one base length and b is equal to the other base length and h is the height of the trapezoid.
a = 7
b = 13
h = [tex]\sqrt{55}[/tex] ([tex]3^{2}+h^{2} = 8^{2}[/tex])
Plug into the equation:
[tex]A = \frac{7+13}{2} *\sqrt{55}[/tex]
A = [tex]10\sqrt{55}[/tex] or ≈74.2m²
Second trapezoid (right):
Not a normal trapezoid (split into a triangle and a square)
Let's solve for the triangle first:
using [tex]sin(30) = \frac{x}{12}[/tex] to find the right-hand side of the triangle we get x = 6
because this is a 30 60 triangle, the last side has to be [tex]6\sqrt{3}[/tex]
Now we can calculate the area of the figure:
Triangle is [tex]\frac{1}{2} * 6 * 6\sqrt{3} = 18\sqrt{3}[/tex]
Rectangle is 6 * 9 = 54
Area = [tex]54 +18\sqrt{3}[/tex] or ≈ 85.2 in²
Find an expression for the height of a parallelogram whose area is represented by 2x^3 − x^2 − 20x + 3 and whose base is represented by (x + 3).
Answer:
The height of parallelogram is [tex]2x^2-7x+1[/tex]
Step-by-step explanation:
Area of parallelogram =[tex]Base \times Height[/tex]
Area of parallelogram = [tex]2x^3 -x^2 -20x + 3[/tex]
Base of parallelogram = x+3
So, [tex]2x^3-x^2-20x + 3 = height \times (x+3)[/tex]
[tex]\frac{2x^3- x^2 -20x + 3}{x+3}= height\\2x^2-7x+1=Height[/tex]
Hence The height of parallelogram is [tex]2x^2-7x+1[/tex]

Answer & Step-by-step explanation:
Replace ? with =, >, or < to make the statement true. 12 ÷ 4 + 13 ? 2 + 22 ÷ 2
Answer:
>
Step-by-step explanation:
On the left side, we divide first: 12/4=3
On the left side, we get 3+13, which equals 16.
On the right side, we also divide first: 22/2=11
On the right side, we get 11+2, which equals 13.
We know that 16 is larger than 13, so
12 ÷ 4 + 13 > 2 + 22 ÷ 2

You invest $5000 into an account earning 4% interest compounded quarterly. Write an
equation to represent the amount of money you will have in your account after 8 years?
Answer:
A (in $USD) = 5,000(1 + .04/4)^4(8)
A = 5000(1 + 0.01)^32
A = 5000(1.01)^32
A = 5000(1.37494068)
A ≈ 6874.7034
A = $6875 or $6875.7 (depending on rounding requirement)
Step-by-step explanation:
Compound Interest Formula
A = P(1+ r/n)^n(t)
A is the amount in the account after t yearsP is the principal (original amount invested)r is the annual rate, expressed as a decimaln the number of times the interest is calculated a year*t is the number of years*If the interest is compounded monthly n = 12, if quarterly n = 4, if daily n = 365.

What is the volume of a cylinder with a height of 17 cm and a base radius of 7 cm to the nearest 10th
Answer:
Step-by-step explanation:
volume =πr²h=π×7²×17≈2616.9 cm³
The volume of a cylinder is 2616.95 cubic centimeters.
What is volume?It is defined as a three-dimensional space enclosed by an object or thing.
We have:
The height of the cylinder h = 17 cm
Base radius of the cylinder r = 7 cm
We know the volume of a cylinder is given by:
[tex]\rm V = \pi r^2h[/tex]
[tex]\rm V = \pi\times 7^2\times17[/tex]
V = 833π cubic centimeters
V = 833×3.141592
V = 2616.94668 cubic centimeters or
V = 2616.95 cubic centimeters.
Thus, the volume of a cylinder is 2616.95 cubic centimeters.

There are crows and groundhogs in a field. All of them together have 15 heads and 40 legs. How many of each animal are in the field?
Answer:
idk
Step-by-step explanation:
I'm going to do some deep research to find the answer. One sec
Answer:
There are 5 groundhogs and 10 crows.
Step-by-step explanation:
Ok, so there are 15 animals and 40 legs. So, groundhogs have 4 legs while crows have 2. Lets say x= our groundhog legs, and y= our crow legs. Our equations are 4x+2y=40 and x+y=15. Now that we have the equations needed we just have to solve them. Now we subtract the two equations from each other. So, this would get,
4x+2y=40
- x+ y=15
--------------------
3x+y=25.
Now we need to subtract x to the other side. So, now we have y=25-3x. The only solution to this problem is (5,10). 25-3(5)=25-15=10. To check this lets put them into our original equations, 4x+2y=40 and x+y=15. So, 4(5) + 2(10)=20+20=40, and 5+10=15! So there's your answer.
